The 2011 SATELLITE Conference had more than 10,000 attendees from 70 countries taking place in Washington D.C. last week. The exhibition grew to more than 325 companies with more than 60 of which are exhibiting for the first time. Although there was an outdoor exhibit this year, it was very small (two companies – Hughes and L-3), but I think this is great idea if they can get more participation next year. Traffic seemed little better than last year and there were actually small crowds at the doors just prior to opening on the first 2 days.
The SATELLITE 2011 Conference began with chief executives from the world’s four largest satellite operators discussing the future of the satellite marketplace. The conference’s other sessions included High Throughput Satellites: Broadband and Beyond; A New Generation of MSS Terminals: What’s Next for MSS Equipment: Hosted Payloads: Thinking Outside the Box; 3-D TV via Satellite: Building Foundations for Success: Earth Observation- A Luxury Item or a Commodity?; How Can Commercial Satellite Providers Best Meet Government Requirements for COTM?; Satellites and Broadcasting: A 30-Year Warning, among many others.
There were a large number of RF/microwave companies attending (seemed like more than in the past), ranging from T&M to antennas to components. The best represented were filter and high power amplifier companies along with the system companies like L-3, Cobham, Rockwell Collins, Boeing, GD, LMC, Hughes, Thales, EADS, etc. Here is what the RF/microwave companies we visited were showing off in their booths including some selected video demos:
Actox is the first manufacturer to introduce a 7 W Extended (13.75-14.5GHz) Ku-Band BUC, which has been requested by many users. It offers low cost and power consumption in a small package. The unit features a double L.O. (12.80 and 13.05 GHz), field exchangeable IF connector, digital temperature compensation, L.O. and Amplifier LED’s.
Advantech Wireless released a new smaller, lighter, compact mobile transportable DVB-RCS hub. The new hub is really a turn-key satellite communications system which can be deployed in less than 1 hour, to enable a wide range of public and/or private network topologies with satellite interactive terminals. I was impressed with their broad line of GaN Ku- and X-band BUCs ranging from 50 to 500 W. The 500 W Ku-band unit was on display connected to a system.
Anritsu Company introduced the MS272xC Spectrum Master series that provides the broadest frequency range ever available in a handheld spectrum analyzer.
